I have a longtime customer, who decides to move to a new location his Avaya switch was starting to die out and out of the blue he picks up an NEC Electra Elite IPK then calls me and says I need you to install it. I'm an AVAYA guy have been for a long time now and this guy is more of a friend than a customer now. I now have a huge headache cause I can't find a system hardware manual to hook the new phone switch up. Can anyone please help.

Thanks,

Dave
